Don't waste your money, get the Hanna kit insteadBy Philon 11/12/2014

Phil wouldn't recommend this product to a friend

I've used this weekly for the last 3 month and it reads .08 every time. I know for a fact my water is not more than .04. If anything I have a difficult time to maintain .02-.04 for sps coloration because of the reactors I'm using. Garbage test kit.

Some of the older kits were sold with a bad color wheel. This has since been corrected. Very easy kit to use; though it can be difficult to tell the difference between the colors at the lowest of PO4 levels.

Will not read lower than .08By TrevorJohnsonon 4/17/2013

TrevorJohnson wouldn't recommend this product to a friend

Every thing I have tested all read .08 .
My tank water- Fresh made salt water- Natural seawater- 0 tds rodi water.
All test at .08 and I have had 6 other people run the tests and they all get .08 also

InaccurateBy Matton 1/13/2013

Matt wouldn't recommend this product to a friend

Like others on here have mentioned, this test kit is not accurate. I obtain readings of .08 to .16 when it should be reading zero like on freshly made saltwater, RODIwater, and the water coming out of my gfo reactor (fresh gfo just installed before taking the reading).

always 0.08By ecfarron 12/30/2012

I bought this kit. I always got a reading of 0.08 on my display tank, gfo reactor output, and my r/o output with brand new filters.
I told my lfs who communicated with red sea. They sent me a new set of reagents a and b. Guess what. EVERYTHING READS 0.08 AGAIN. Red Sea has bad quality control. Never will buy a red seak kit again.

always get 0.08, have issue with this test kitBy Jasonon 10/4/2012

Jason wouldn't recommend this product to a friend

I have tried using this test kit, but no matter how I test it, and when I test it, I always get a 0.08. Then I found out there's an issue with this test kit from forums.

a lot easier to read than other kits out there and results match the colorometer I bought later.

took me a bit to see the color differences but once I got what i was looking for this is way easier to read than the salifert kit I was useing.

False readingsBy Mikeon 1/19/2012

Mike wouldn't recommend this product to a friend

There should be a warning on the add for this product. Many people get a false read of .08 no matter what kind of light they use. Red Sea knows about it but they fail to warn people before selling it. I'll stick with Salifert.
